-HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application led November 16, 1904. Serial No. 233,012.

A of Virginia, have invented certain new and useful Improvements inHydrocarbon-Burners, of which the following is a specification. Thisinvention is a burner of novel structural organization intended mostspecially for utilizing crude petroleum as fuel and for steam boiler andother furnaces requiring intense heat and an extended heating-surface.

The chief objection to the successful utilization of crude petroleum asfuel is the residue resulting from combustion, same depositing in thepipes, connections, and adjunctive parts of the burner and impeding thepassage of the oil, vapor, and gases. This invention provides for theseparation of the gaseous mixture, the more volatile and rarefied fluidpassing to a high burner or burners and the heavy mixture to arelatively low burner of such proportions as to admit of any residue ordeposit being easily and quickly removed. The burner is also constructedwith a view to admit of access being had to the parts for cleaning atregular intervals when the device is in constant use, thereby assuringits effectiveness at all times--an essential attribute of a burner ofthis type.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge ofthe details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodimentthereof is shown in the accompanying drawings, in which- Figure 1 is aperspective View of a burner embodying the invention. Fig. 2 is acentral longitudinal section thereof.

Corresponding and like parts are referred to in the followingdescriptionand indicated in both views of the drawings by the samereference characters.

In its organization the burner comprises complemental generators 1 and2, the latter acting in the capacity of a superheater for rarefying orthoroughly volatilizing the vapors passing thereto from the primarygenerator 1. The generators 1 and 2 are of similar construction, eachconsisting of a circular rim or band, and heads 3 and i threaded intothe rim or band and provided externally with angular projections 5 forreception of a wrench, Spanner, or other tool by means of which saidheads are tightened or loosened as may be required. The generators arecomparatively shallow, so as to insure every portion of the liquid orvapor coming in contact with the heated walls, so as to be ashed orrapidly converted into gaseous vapor. A

pipe 6 connects the generators 1 and 2 and is thereof at a pointdiametrically opposite the pipe 8 and'is provided with a valve 11. Thepipe 10 is adapted to be connected to a suitable source of suppl y, theoil being forced therethrough under pressure by means of a pump or otherequivalent means. A steam-pipe 12 connects with the oil-supply pipe 10at a point between the valve 11 and the generator 1 and is provided witha valve 13. The oil and steam commingles at the juncture of the twopipes 10 and 12, the oil being heated and atomized and delivered in thiscondition into the generator 1, where the major portion is convertedinto gaseous vapor and passes through the pipes 6 and 8 into thegenerator 2 and is superheated and thoroughly vaporized so as to beconsumed at the burners.

A header 14 lis arranged transversely of the complemental generator andis composed of a series of pipe-fittings-such as Ts, nipples, andfour-way couplings, the latter being arranged at the extremities of theheader, asindicated at 15.

A pair of burners 16 are located upon op-- posite sides of thesupply-pipe 10 and are inclined slightly to the horizontal, so as todirect their fiame upon the generator 1. The burners 16 may be of anystructural type of the Bunsen variety and are connected to the header 14by short vertically-disposed pipes provided with valves 17, by means ofwhich the supply of gas is controlled. Plugs 18 close the outer ends ofthe burner-tubes 16 and when removed admit of access to the burners forremoval of any residue which would tend to plug the same. A third burner19 is arranged below the plane of the complemental generators and isconnected to the header 14 by means of a pendent pipe 20, provided witha valve21. A plug 22 closes the outer end of the burner-tube, for apurpose similar to the plugs 18. The burner 19 is centrally disposed andis of larger proportions than either of the burners 16 and receives theheavier gases, the lighter or more volatile gases passing to the burner16. A spreader 23 is arranged below7 the generators 1 and 2 and in thesame plane with the burner 19 and is preferably constructed ofrefractory material, such as iire-clay, and consists of a slab or tilelhaving a plurality of ducts 24, through which i the vapor from thegenerator 19 passes. Longitudinal pipes 25 connect the opposite ends ofthe header 14 with a transverse pipe 26 at the rear of the burner,four-way iittings 27 coupling the pipes 25 and 26, and, like thefour-way ttings 15, have their outer ends closed by means of plugs 28,which when removed admit of an unobstructed passage through respectivepipes 25 and 26 and the header 14, whereby any deposit of residuum maybe removed. A receiver 29 is coupled to the pipe 26 and generator 2 andacts in the capacity of a storage-chamber for equalizing the supply ofgas to the respective burners and insuring a steady and uniform flame.The ends of the receiver 29 are closed by removable plugs or caps 30 toadmit of the same being easily cleaned.

From the foregoing it will be readily understood that the constructionis such that access may be had to every part for removal of any residueor deposit, thereby assuring the efciency of the burner by proper careat stated intervals. When starting the burner, it is necessary to heatthe generators 1 and 2, and this may be accomplished in any way, eitherby the application of a torch or by applying a fire around the same oflight kindling or in any manner determined upon. After the generatorshave been heated the valves 1 and 13 are opened and the atomized oil isdelivered into the primary generator 1 and is wholly or partly vaporizedand passes from the generator 1 into the generator 2 and is superheatedor completely vaporized or rarefied and passes from thence through pipes26 and 25 into header 14 and from thence to the respective burners 16and 19. It will be observed that the component parts of the burner arecompactly arranged and located within the heating zone of the burners,so as to prevent condensation of the vapors, and the controlling-valvesare so arranged that any part may be temporarily shut off to admit ofinspection for cleaning after the required plug or plugs have beenremoved.

In ahydrocarbon-burner, the combination of the generators 1 and 2, theconnection 6 between said generators, the transverse pipe 26 connected-with the generator 2, the header 14, and the connections 25 between thetransverse pipe 26 and the header 14, the upper burner 16, and the lowerburner 19 having connection with the header14 as specified.
